One Colorado destination known for its jaw-dropping beauty is Island Lake in Southwest Colorado near Silverton. Tucked away in the San Juan National Forest, Island Lake is one of four bright blue lakes that hikers trek to in the Upper Ice Lake Basin. It’s a four-mile trail one way, but it’s definitely worth it, as hikers make the journey past old mining ruins, seemingly endless wildflower fields, and jagged peak after jagged peak.
Island Lake is located at roughly 12,400 feet above sea level.

Island Lake’s bright blue color comes from something called glacial flour, residue found in the snow melt that fills the lake.
